Expected Behaviour

A tooltip should be hidden after mouse is out of an element which generates the tooltip.

Current Behaviour

Even I move the mouse cursor out of an element, the tooltip is still visible. It is really annoying problem which doesn't allow in come cases modify/press other UI elements.

Context

I have the problem each time when I try to demonstrate CVAT to internal/external customers. It is a really critical usability issue.
